To @ZZ whom, it may concern.-

Be it known that l, DAVID ll. HOUSTON, a citizen of the United States, residing at Hunter, in the county of Cass and State ot' `North Dakota, have invented certain new and useful Improvements in Cameras; and l do hereby declare the following to be a full, clear, and exact description ot the invention, such as will enable others skilled in the art to which it appertains to malte and use the same.

My invention relates to photographic cameras, and has ior its object the construction oi' a compact camera carrying lenses on tivo opposite si( espaliereby the camera is adapted to do avarietyot work, such as ordinary views and stereoscopic vievvs or views of ordinary angle and views of wide angle.

rllhe camera has a central portion for exposing the sensitized surfaces to the actinic action of light passed through the lenses and lenses adapted to do special Work, mounted so as to be iccused in at one side of the camera, and lenses adapted to do a different class of Work, mounted seas to be focused in at the opposite side of the camera, whereby a combined capacity of two cameras or" difterent qualitications is had in one compact piece of apparatus having one central eizposin g portion.

My invention further combines a construction at once novel and useful, and by said construction the lens or lenses on one side can be focused as a magnifying-glass upon the focusing-surface, and said lenses can be utilized to lool; through to observe the focusing of the lens or lenses on tue opposite side ot the camera, f-.vhereby a separate focusingglass and a focusing-cloth are simultaneously dispensed with.

Figure l is a central sectional plan vieu of the camera extended, taken on the line C D of Fig. 2. Fig., 2 is a longitudinal vertical sectional view of the camera extended, taken on the line A E of Fig. i. Fig. 3 is avertical cross-.sectional vienT ot the camera closed, taken on the line A B of Fig. l. Fig. e is a perspective vien7 of a roll-holder that may be used with my camera.

Similar letters of reference refer to similar parts in all of the views.

My invention comprises a camera which may be constructed with opposite sides R,

` folding outwardly from one base T, anda bellows .V on opposite sides,cXtendiugoutwardly from a central portion E. Said portion E may have partial divisions F, carrying springs ll, Fig. which springs H press outwardly upon the holders N, Fig. 3, or focusing-trame P, the case may be. Between the partial divisions F the re fersible focusing frame and glass F can be stored when not in use, as seen in 3, and on opposite sides ot' the focusring-glass the plate-holders N can be carried ready vtor use, as seen in Fig. 23, which plateholders can be inclosed by the light-tight central cover l. For the pur iose of adjusting and indicating the extent of projection of the lenses l arrange centrally upon each of the hinged sides of the casing the plates lli, provided each with graduated scale M and having a channel M2, which receives the adjusting-seresT his, and by means of this construction it will be readily understood that the lenses can be adjusted to any desired projection. sitized film can be substituted for the plate or cut-hlm holders, and the roll-holder can be reversed in the central portion, so as to receive impressions through lenses on either ot two opposite sides ci the camera, as desired.

l am Well aware that the construction of many parte of my invention may be of any general construction at present used in the manufacture of cameras; but claim as my invention the combination of parts as more explicitly set forth in the claims forming part oie this specilication.

l claim as my inventionl. ln a photographic camera the combinaion a casing having a central portion adaptd i" holding and exposing sensitized photoraphic surfaces to the actinie action oi light assed through lenses, a light-tight cover on e said central portion, extensible bellows attached on opposite sides of the said central portion, two sides of the casing folding outwardly and forming with the base of the casing a continuous base adapted to support said bellows when extendeddenses mounted on the frontend of said bellows, and means whereby said lenses can be adj usted to focus on sensitized photographic surfaces in said central portion of said camera.

2. ln a photographic camera the combinar-H do (n cr :TU

A roll-holder L for using a rollable sen-V tion of a easing having a central portion adapted for holding-and exposing sensitized photographic surfaces to the act-inic action of light passed through lenses, a light-tight cover on the said central portion, folding sides hinged to the base of said casing and adapted to form with the base of the casing a continuous base, a divided bellows connected at its inner end to one side of said central portion, a pair of lenses of equal foci mounted and connected tothe outer end of the divided bellows, a lens mounted and connected to the outer end of the single bellows, and means for supporting, adjusting, and indicating the eX- tent of projection of said lenses.

3. In a photographic camera the combination of Va casing having two of its opposite sides folding outwardly, said folding sides adjustable to form one rigid continuous base with the bottom of the camera-casing, a central portion in said casing fitted to hold sensitized-surface holders, said central portion having an opening adapted to admit the said holders, a light-tight door closing said pening, bellows attach ed at opposite interior sides of the said central portion, said bellows eX- tensible outwardly on opposite sides of the easing, lenses mounted to close the outer ends of the bellows, and means for adjusting the focal position of the lenses to focus upon sensitized surfaces in the central portion of th casing.

4. In a photographic camera the combination of a casing having a central portion adapted to receive holders for sensitized surfaces, said central portion having stops on opposite sides of the said central portion, an opening in said central portion adapt-ed to admit the said holders, said stops adapted to limit the position of the holders and stay the saidA holders at opposite' sides of the said central portion, a door closing said opening in the central portion, folding sides hinged to the casing on two opposite sides, said folding sides fitted into the casing, said folding sides adapted to vfold outwardly and form a continuous base with the bottom of the camera-casing, said continuous base itted to support standards carrying lenses connected to the outer ends of the bellows, and said standards adjustable upon the folding sides when opened outwardly.

In testimony whereof I affix my signature in presence of two witnesses.

DAVID I-I. HOUSTON.
